The human cerebellum is split in half while the sheep cerebellum is one mass for a few reasons. This is because the human brain is more complex.
The human brain is larger. The positioning of the hind brain is different, due to the erect position of humans. Convolutions are increased in humans (increases surface area). The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors). There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).
The human pons is larger (pons serves as a bridge of communication between cerebellum and cerebrum) The sheep medulla is larger (Medulla controls vital functions (breathing and heart beat))
about 450.000 while the human population is only about 300.000
Sheep have a similar reproductive system to humans, with a vaginal canal that leads to the cervix and uterus. While there are similarities in structure, there are also differences in size and function between sheep and human vaginas. Additionally, the reproductive cycles and anatomy may have variations that are specific to each species.
Cerebrum has the primary motor are which controls our body movement while the cerebellum is responsible for balance and coordination.
The cerebellum, also known as the 'little brain' is in charge of general locomotion. While the cerebellum does not initiate motion, it is charged with smoothing it out.
A sheep is a type of animal, while a ewe is a female sheep.
The cerebellum works in conjunction with the motor cortex to produce skilled, coordinated movements. The motor cortex initiates voluntary movements, while the cerebellum helps to smooth out and refine these movements to make them more accurate and precise. Damage to the cerebellum can lead to impairments in coordination and motor control.
In a sheep brain, the olfactory bulbs are much larger than in a human brain.http://wiki.answers.com/Q/How_do_the_sizes_of_the_olfactory_bulbs_of_the_sheep_brain_compare_with_those_of_the_human_brain"
The cerebellum and the pons are not derived from the cerebral cortex. They are separate structures in the brain that have different functions. The cerebellum is involved in motor control and coordination, while the pons plays a role in regulating functions such as breathing and sleep.
No a ewe is a female sheep, while a doe is a female goat.
A human brain is larger overall, sheep brains have larger olfactory bulbs though, they also have an area on the sides, around where the temporal lobe is where their eyes go, this causes an indentation humans don't have.
